FW-190 "Dora"

The Fw 190 D (nicknamed the Dora-9 Dora-Neun or Long-Nose Dora Langnasen-Dora) was introduced for one primary reason: high altitude performance. While previous versions of the Fw 190 were very effective at low and medium altitudes, they lacked performance at the higher altitudes at which the American heavy bombers (such as the B-17) and accompanying Allied escort fighters operated.
